Cement yog cov khoom siv khi siv hauv kev tsim kho whereas clinker yog siv los tsim cement . Lub ntsiab qhov sib txawv ntawm clinker thiab cement muab hauv qab no. Clinker yog cov khoom siv nodular uas yog siv los ua cov ntawv khi hauv cement cov khoom. Qhov tseem ceeb siv ntawm clinker yog tsim cement.
Kuj nug, dab tsi yog txhais los ntawm cement clinker?
Portland cement clinker yog cov khoom siv grey tsaus nti ua los ntawm cov cua sov hauv av limestone thiab av nplaum ntawm qhov kub ntawm li 1400 ° C - 1500 ° C. Cov nodules yog av mus rau ib tug zoo hmoov los tsim cement , nrog ib qho me me ntawm gypsum ntxiv los tswj cov khoom siv.
ntau npaum li cas yog ib tug cement clinker? Ordinary Portland cement tuaj yeem muaj txog li 95% clinker (lwm 5% yog gypsum). Qhov nruab nrab tam sim no clinker -rau- cement ratio ntawm tag nrho cov cement hom hauv EU27 yog 73.7% 1.
Khaws qhov no hauv kev xav, vim li cas clinker siv hauv cement?
Portland cement clinker yog av rau hmoov zoo thiab siv raws li tus binder hauv ntau cement cov khoom. Ib me ntsis gypsum yog qee zaum ntxiv. Nws kuj tseem tuaj yeem ua ke nrog lwm cov khoom xyaw nquag lossis cov tshuaj sib xyaw ua ke los tsim lwm hom cement suav nrog: av granulated blast rauv slag cement.
Dab tsi yog clinker zoo?
Feem ntau clinker zoo yog txiav txim los ntawm kev ua haujlwm hydraulic ntawm cov cement ua los ntawm cov clinker . Hydraulic kev ua tau zoo ntawm cov cement npog kev txhim kho lub zog, teeb tsa cov yam ntxwv, ua haujlwm tau zoo thiab ua haujlwm ntev thiab sib xws ntawm cov yam ntxwv ntawm kev ua haujlwm hydraulic.

Dab tsi yog qhov txawv ntawm qhov ua tau zoo thiab cov khoom lag luam teb thiab cov ntsiab lus ntawm kev lag luam uas txhua qhov ua haujlwm zoo tshaj?
Lub tuam txhab muaj peev xwm ua kom tau raws li cov neeg siv khoom xav tau raws sijhawm yog hu ua Kev Ua Haujlwm Zoo, thaum ua haujlwm tau zoo yog lub tuam txhab muaj peev xwm xa khoom raws li tus neeg siv khoom xav tau nrog tsawg kawg ntawm cov khoom siv raw, kev ua haujlwm thiab tus nqi
Dab tsi yog qhov txawv ntawm qhov point thiab nonpoint qhov chaw ntawm dej paug?
Piv txwv li, cov dej tso tawm los ntawm cov chaw tsim khoom lag luam ntawm qee yam lossis cov chaw kho dej khib nyiab. Cov chaw uas tsis yog cov ntsiab lus suav nrog kev khiav tawm ntawm thaj av ua liaj ua teb uas tuaj yeem ntxuav cov chiv lossis lwm yam tshuaj rau hauv pas dej lossis dej ntws - qhov no yuav tshwm sim ntau txhiab square kilometers
Dab tsi yog qhov txawv ntawm qhov rov qab los ntawm peev thiab rov qab los ntawm peev?
Ua ntej, qee qhov kev txhais. Rov qab los ntawm peev ntsuas qhov rov qab uas qhov kev nqis peev ua rau cov neeg koom nrog peev. Rov qab los ntawm peev (thiab ntawm no Idiffer nrog qee cov ntsiab lus) yog thaum tus neeg ua lag luam tau txais ib feem ntawm nws cov peev txheej qub rov qab - suav nrog cov nyiaj tau los ntawm cov nyiaj tau los - los ntawm kev nqis peev
Dab tsi yog qhov txawv ntawm qhov cuam tshuam qhov (socket) thiab lub qhov (socket) pa?
Rau kuv qhov kev paub qhov sib txawv yog nqes mus rau cov khoom siv Qhov saum npoo-hardening ua rau muaj kev cuam tshuam cov qhov (socket) kom nqus tau qhov hloov pauv tam sim ntawd (aka 'kev cuam tshuam') zoo dua. Nrog rau kev cuam tshuam txaus txaus, lub qhov (socket) tsis tu ncua tuaj yeem tawm ntawm cov duab vim tias cov hlau siv muaj softer
Dab tsi yog qhov txawv ntawm qhov kev thov thiab qhov xav tau ntawm cov khoom hais tias mis nyuj?
Dab tsi yog qhov txawv ntawm qhov kev thov thiab qhov xav tau ntawm cov khoom, hais mis nyuj? Kev xav tau yog kev sib raug zoo ntawm ntau tus nqi thiab qhov xav tau ntawm cov nqi ntawd. Kev xav tau ntawm cov mis nyuj yog qhov kev sib raug zoo ntawm tus nqi sib txawv ntawm cov mis nyuj thiab qhov xav tau ntawm cov nqi ntawd
